Sure, those how-to sex videos with the soft-focus ads seem a little embarrassing, but some are based on legitimate research and have great ideas. We watched the "Better Sex Video Series: Sexplorations" tapes with pen and paper in hand—so you won't have to (although you might like 'em!). Here, the best take-away tips.
On average, men get three to five erections per night in addition to erections that result from sexual activity. Dr. Ajay Nehra, a professor of urology at the Mayo College of Medicine, says erections are important for penile muscle health because they bring much-needed oxygen to the penis. This helps maintain the health of the nerves -- making sex a healthy habit.
One recent Finnish study showed that men who had sex once a week were half as likely to develop erectile dysfunction as men who had sex less frequently. In women, more frequent sex also stimulates circulation to the genitals. In turn, this enhances lubrication and the elasticity of vaginal tissues -- both of which go a long way toward boosting a woman’s enjoyment of sex.
Some researchers believe there’s a psychological component as well. You may stop wanting sex if you go a long time without it. This is partially because ”turning off" helps you avoid feelings of sexual frustration. Having more frequent sex can actually keep you interested in sex.
